Description

Technical Field

[0001] This invention relates to the field of cigarette ventilation technology in cigarette factories, specifically an energy-saving ventilation device for cigarette factories. Background Technology

[0002] A ventilation system is a device that facilitates the exchange of indoor and outdoor air through mechanical or natural means.

[0051] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0052] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application, however, can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the scope of the present application, and it is understood that variations can be made in view of what has been described heretofore, without departing from the spirit of the present application. Accordingly, the present application is not limited to the specific embodiments described below.

[0053] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments.

[0054] The present application discloses an energy-saving ventilation device for a cigarette factory, which refers to Figures 1-10 , comprising:

[0055] The workbench 1 and the carrying manipulator are used for carrying and placing cigarettes; the supporting table 3 is fixedly installed on the workbench 1; the rotating part 4 is connected with the workbench 1 and located between the supporting table 3 and the workbench 1; the telescopic air cylinder 7 is fixedly installed on the supporting table 3, and the lifting seat 8 connected with the output end of the telescopic air cylinder 7; the ventilation assemblies 63 are a plurality in number and uniformly arranged on the lifting seat 8; the negative suction unit 5 is uniformly arranged on the supporting table 3 and used for placing cigarettes; the ventilation unit 6 is arranged on the supporting table 3; the ventilation unit 6 comprises the ventilation assemblies 63; the ventilation assembly 63 comprises the protective cover 631 fixedly connected with the lifting seat 8, the fixing frame 634 and a plurality of sound detectors arranged in the protective cover 631, the adjusting mechanism 632 arranged in the fixing frame 634, the moving seat 633 connected with the adjusting mechanism 632, and the correction part 635 and the suction part 636 respectively arranged on the moving seat 633; the gas entering amount from the air inlet 6361 can be changed through the work of the correction part 635;

[0056] At this time, the first mode is that when the correction part 635 works, the working correction part 635 can drive the sealing plate 6366 to move through the cooperation work of the driving disc 6359 and the ventilation rod 6356 arranged, so that the sealing plate 6366 can move away from the moving seat 633, so that the gas can enter the moving seat 633 from the axis direction of the ventilation rod 6356, and the position of the communication disc 6369 can be adjusted, so that the flue gas can enter the moving seat 633 from the first filter screen 6363;

[0057] The second mode is: when the direction of the inhaled smoke needs to be changed, the air inlet amount into the first air inlet 6357 is changed at this time, so that the movable disc 6355 can move in the area between the moving seat 633 and the adapter seat 6354, and then the moving adapter seat 6354 can drive the air inlet rod 6356 to move, so that the sealing plate 6366 can abut against the moving seat 633, and the smoke passes through the second filter screen 6364 into the moving seat 633, and by changing the air exchange position of the smoke, the smoke suction mode of the second mode can be selected according to the burning degree of the cigarette. When the cigarette just starts to burn, the smoke suction mode of the second mode is selected to avoid excessive negative pressure air suction, which causes the cigarette to burn too fast. When the cigarette is more than half burned, the smoke suction mode of the first mode is used at this time, which can ensure that the negative pressure suction work of the smoke can be completed, thereby completing the air exchange work.

[0058] The correction part 635 comprises an adapter seat 6354 screwed with the moving seat 633, a correction nut 6351 screwed with the adapter seat 6354, a movable disc 6355 located between the moving seat 633 and the adapter seat 6354 and in the adapter seat 6354, an air inlet rod 6356 penetrating through the movable disc 6355, a second spring 6353 for connecting the movable disc 6355 and the adapter seat 6354, and a first spring 6352 for connecting the air inlet rod 6356 and the correction nut 6351; the moving seat 633 is further provided with a first air inlet 6357; the adapter seat 6354 is provided with a stepped groove; the air inlet rod 6356 is provided with a gas conveying channel 6358, a driving disc 6359 located at one end away from the correction nut 6351 and arranged on the air inlet rod 6356, and a clamping protrusion connected with the driving disc 6359 and inserted into the suction part 636; the gas conveying channel 6358 is in F-shaped structure, and the driving disc 6359 is in disc structure and uniformly provided with a plurality of gas conveying channels in the inside; the gas conveying channels are in communication with the gas conveying channel 6358 and used for injecting gas into the suction part 636; the driving disc 6359 abuts against the suction part 636;

[0059] When the position of the communication disc 6369 needs to be adjusted to change the suction position of the smoke, the gas amount between the moving seat 633 and the adapter seat 6354 can be changed by changing the gas conveying amount or suction amount in the first air inlet 6357 at this time. Since the first spring 6352 and the second spring 6353 are in a compressed state, the movable disc 6355 can be driven to move, so that the movable disc 6355 can move in the adapter seat 6354, and then the position of one end of the air inlet rod 6356 can be changed. The moving air inlet rod 6356 can drive the driving disc 6359 to move, so that the communication disc 6369 can be pushed to move in the axial direction of the moving seat 633.

[0060] When the sealing plate 6366 is away from the moving seat 633, the gas can enter the moving seat 633 from the axis direction of the moving seat 633 through the first filter screen 6363, and the gas adsorption work is completed;

[0061] When the sealing plate 6366 is close to the moving seat 633, the gas can enter the moving seat 633 through the second filter screen 6364, and the gas adsorption work is completed;

[0062] In a further embodiment, the gas outlet end of the gas inlet channel on the driving disc 6359 is arranged on one side of the driving disc 6359, and the side provided with the gas outlet end is closer to the air inlet 6361 than the other side. In this embodiment, the negative pressure air suction work is performed through the air inlet 6361, and then the air inlet end of the air outlet 6362 is blocked by the ventilation rod 6356. At this time, the smoke adsorption work can be completed, and then after the cigarette completes the combustion work, the cigarette is replaced. At this time, by changing the position of the ventilation rod 6356, the gas outlet end of the gas inlet channel abuts against the inner wall of the moving seat 633. At this time, the F-shaped gas inlet channel 6358 can communicate the air inlet 6361 and the air outlet 6362, and the self-circulation work of the gas can be performed. Under the premise that the negative pressure air suction work of the air inlet 6361 is not stopped, the smoke adsorption work can be stopped, thereby avoiding the cigarette from entering the device due to the breakage of the cigarette caused by misoperation or other conditions during the installation process;

[0063] In a further embodiment, the deformation amount of the first spring 6352 and the second spring 6353 can be adjusted by the setting of the correction nut 6351, so as to adjust the initial position of the ventilation rod 6356, thereby ensuring that the correction part 635 can normally work;

[0064] When axial and circumferential double-direction adsorption is adopted, a wider area can be covered, and it is suitable for large amount of smoke rapid collection scene. When switching to circumferential adsorption, the target area can be accurately focused, and irrelevant gas interference is reduced. At the same time, the device selects according to the burning time of the cigarette, avoids the interference of the gas generated during the adsorption on the detection of the sound detector, so as to not only perform the air exchange work of the smoke to avoid the high smoke concentration affecting the transmission of the sound emitted by the cigarette during the smoke combustion, but also avoid the influence of the negative pressure gas on the cigarette, causing the cigarette to burn too fast and the detection result to have a large error.

[0066] When it is necessary to change the mode of air suction, the clamping pipe 63610 can be pushed to move by the driving disc 6359, so as to adjust the position of the communication disc 6369 in the moving seat 633, which not only can seal and block the moving seat 633 by the sealing plate 6366, but also can change the suction area of the gas from the moving seat 633 in the circumferential direction, so as to select the corresponding mode according to the different combustion degrees of the cigarette, so as to complete the air exchange of the smoke, avoid the too high smoke concentration, and cause the cigarette to be extinguished and the cigarette detection work to fail.

[0076] Working principle: when the position of the communication disc 6369 needs to be adjusted to change the suction position of the flue gas, the amount of gas in the first air inlet 6357 or the suction amount can be changed to change the amount of gas between the moving seat 633 and the adapter seat 6354. Since the first spring 6352 and the second spring 6353 are in a compressed state, the movable disc 6355 can be moved, thereby changing the position of one end of the ventilation rod 6356.
